PRINTING-PRESS- SPEGIFICATION forming part of Letters Patent No.773,766, dated November 1, 1904.

Application filed February 15, 1904. Serial No. 193,563-

' To all whmn it Wwty concern:

Be it known that 1, Aims V. PROOTOR, of Billerica, in the county ofMiddleseX and State of Massachusetts, have invented certain new anduseful Improvements in Printing-Presses, of which the following is aspecification.

This invention relates to printing-presses adapted particularly forprinting menu-cards and other relatively small sheets and to be operatedby hand.

The invention has for its object to provide a simple and effectiveprinting-press adapted to be operated with satisfactory rapidity and tooperate efficiently.

The invention consists in the improvements part of this specification,Figure 1 represents a side view of a press embodying my invention. Fig.2 represents a plan view of the same. Fig. 3 represents asection on line3 3 of Fig. 2. Figs. 4 and 5 represent elevations of the opposite sideof the machine from that shown in Fig. 1. Fig. 6 represents a plan viewof a modification hereinafter described. Fig. 7 represents a section online 7 7 of Fig. 6.

The same reference characters indicate the same parts in all thefigures.

In the drawings, (4 represents a slide or carriage movable in guides ona base or support a. To the slide is aflixed a form I), which inpractice is provided with movable type Z), from which the impression ismade when the machine is operated.

0 represents a frame which is provided with trunnions c, journaled inbearings a on the base a. The frame 0 is provided with an inking-roller(Z and an impression-roller e and is adapted to tilt or oscillate andcause therolls (Z and c to cooperate alternately with the form, theinking-roll (Z applying ink to the type when the form is moving in onedirection, while the impression-roll 6 acts to press the paper againstthe inked type when the form is moving in the opposite direction. Vhenthe frame is in the position shown in Fig. 5, the inking-roll isdepressed and is in (N0 model.)

position to ink'the type, the impressionroll being elevated. lVhen theframe is in the position shown in Figs. 1 and 4, the impression-roll isdepressed in position to cooperate with the form in efiecting animpression on a sheet of paper, the inking-roller being raised. When thecarriage reaches one end of its movement, the frame '0 is automaticallytipped to one of the positions above described, and when the carriagereaches the opposite end of its movement the said frame is automaticallytipped to the other position. The means shown for automatically tippingthe frame in this embodiment of my invention comprise a slide f, whichis supported by the base a and has a limited independent endwisemovement permitted by a block f, afiixed to the base and occupying aslot f in the slide f, said block being shorter than the slot, while theupper and lower Walls of the slot are adapted to slide on the block. The

slide f is provided with an ear f*, having two inclined faces f f 9 grepresent arms aflixed to one of the trunnions-of the frame 0 andarranged to cooperate with the ear f, as hereinafter described. When thecarriage is at the end of its movement, (shown in Fig. 5,) the arm gprojects below the top of the ear f the arm 9 being raised above saidear. The inkingroll is therefore in position to cooperate with the formwhen the latter is moved in the direction indicated by the arrow on Fig.5. When the form approaches the opposite end of the last-mentioned orprinting movement,

a finger (&*'on the carriage strikes the slide f 5 and moves the latterto the position shown in Fig. 4:. This movement of the slide causes thearm 9 to swing upwardly, thus tilting the frame cto the position shownin Figs 1 and 4, the arm g being depressed. The impression-roll is nowin position to cooperate with the form during the opposite or printingmovement of the form. hen the form nearly reaches the end of itsprinting movement, a finger a on the carriage a strikes the slide f andmoves the latter to the position shown in Fig. 5, so that the arm g israised and the frame is returned to the position shown in Fig. 5, theinking-roll being thus depressed and the impressionroll raised. It willbe seen, therefore, that at the end of each movement of the carriage oneof the rollers is moved into and the other out of its operative relationto the form; but while the carriage is moving the frame carrying theroll ers is locked in its tilted position by the arms Q and g, whichrest alternately upon the top of the slide f at each side of themachine, such arm resting upon the end of the upper surface of theslide, as shown in Figs. 4L and The carriage a is reciprocated by ashaft Z, journaled in a bearing affixed to the base,

said shaft being provided with an operating crank or handle 71 and witha gear 7?, meshing with rack-teeth 7', formed on the carriage. Therotation of the shaft Z causes the carriage to move endwise.

The rolls (Z and e are positively rotated by means of a gear Zr, mountedto rotate on one of the trunnions c and meshing with the gear 2' andgears m m, affixed to the shafts of the rolls (Z c and meshing with thegear 70.

0 0' represent ink-distributing rolls which are supported by bearings inthe frame 0, the roll 0 being in contact with the inking-roll.

The shafts of the rolls (Z and e are preferably journaled in boxes orbearing-blocks (Z c, which are adjustable Vertically in slots or guidesformed for their reception in the frame 0. Said blocks may be yieldinglysupported by springs s 3, attached to the frame 0 and holding the blocksagainst stop-screws 25 23, which are adjustable vertically in the frame0. Provision is thus made for vertically adjusting the rolls (Z and eand regulating their pressure on the form and on the paper,respectively.

The slide-operating fingers or projections (6* a are preferably U-shapedwire rods, one arm of each rod being adjustably secured by a set-screw ato an ear o on the carriage, the other arm being offset from thecarriage, as shown in Fig. 2. The slide fis located in the path in whichthe said offset arms move.

In the machine represented in Figs. 1 to 5, inclusive, the bearings (Z2,rising from both sides of the base a, will necessarily restrict thewidth of the card or sheet that is printed. I therefore propose toembody my invention in a machine having a main frame of a somewhatdifferent form, as indicated in Figs. 6 and 7. In said figures the frameis shown as provided with an overhanging arm it, having a dependingfront portion or bracket a, the lower portion of which has a bearing forthe outer trunnion c of the frame 0. It will also be seen that in thisform the arms 9 g extend upward instead of downward from the trunnion cand the block f and slide f are carried by the face of the bracket a. Itwill be understood that in this form the ends of the fingers a a" willbe in a plane sufficiently elevated to be struck by the slide 7. Thisconstruction enables a sheet of paper of any length to be inserted onthe line 40.

3. A printing-press comprising a movable form-supporting carriage, afixed support therefor, an oscillatory frame pivoted to said support andhaving an inking-roll and an impression-roll located at opposite sidesof the center of oscillationof the frame, an operating-shaft journaledin said support, connections between the shaft and the carriage wherebyrotation of the shaft is caused to move the carriage, and means operatedby movements of the carriage for tilting the frame, means being providedfor locking said frame against oscillation during its movementrelatively to the form.

4. A printing-press comprising a movable form-supporting carriage, afixed support therefor, an oscillatory frame pivoted to said support andhaving an inking-roll and an impression-roll located at opposite sidesof the center of oscillation of the frame, an operating-shaft j ournaledin said support, means for imparting rectilinear motion from the shaftto the carriage, means for imparting positive rotary motion directlyfrom the shaft to the rolls, and means operated by movements of thecarriage for tilting the frame, means being provided for locking said.frame against oscillation during its movement relatively to the form.

6. A printing-press comprising a movable form-supporting bed, a fixedsupport therefor, an arm overhanging said bed and support and having itsouter end above the plane of the form to permit the sheet of paper beingprinted to extend beyond the side of the press, and an inking-roll andimpression-roll supported in said overhanging arm.
